Problems solved by technology

Cutting sutures at the appropriate location may be difficult, particularly during procedures where access is limited, such as arthroscopic surgery.
Capturing a severed portion of a suture may be equally difficult.
The difficulties may be increased when the suture material is relatively hard to cut, such as stai

Embodiment Construction

[0046] Referring now to the drawings in detail, wherein like numerals indicate the same elements throughout the views, FIG. 1 is a top view of suture cutter assembly 2 constructed according to the teachings of the present invention. FIG. 2 is a cross sectional view taken along line 2-2 of FIG. 1. Suture cutter assembly 2 includes tube assembly 4 and cutter assembly 6. Tube assembly 4 comprises grip 8 having two openings 9 for the operator's fingers. Grip 8 is secured to one end of hollow tube 10. Cutter assembly 6 includes knob 12 secured to one end of shaft 14. Although in the embodiment depicted, tube 10 is secured to grip 8 and shaft 14 is secured to knob 12 by respective set screws, any suitable means for securing them together may be used.

[0047] In the depicted embodiment, shaft 14 is rigid and solid, and dimensioned to reciprocate within rigid tube 10. The clearance between shaft 14 and tube 10 provides some resistance to axial movement of shaft 14. Grip 8 includes cylindrica...

Abstract

A suture cutter assembly has a cutter blade axially reciprocable relative to a tube having at least one opening. An offset is in the tube or the cutter blade for capturing of the severed portion of the suture as the blade is advanced within the tube. A suture cutter assembly includes a recess formed in a shaft which is axially reciprocable within a tube. The recess is configured to receive at least a portion of a severed suture segment. The reception of a severed suture segment portion in the recess may reduce crimping of the severed suture segment between the shaft and the tube, thereby reducing the amount of force required to reciprocate the shaft within the tube when the severed suture segment is positioned between the shaft and the tube.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates generally to suture cutters, and is particularly directed to devices for cutting stainless steel sutures arthroscopically. The invention will be specifically disclosed in connection with a device that cuts a suture while capturing the severed segment. The invention will also be specifically disclosed in connection with a device that cuts a suture having a bead attached thereto while retaining the bead and severed segment. It will be apparent to those of ordinary skill in the art, however, that such uses are merely exemplary, and that the embodiments disclosed herein, as well as their variations, may be used in a variety of alternative ways. [0002] The present invention also relates to knot-pushers, and includes, but is not limited to, devices capable of both pushing suture knots and cutting sutures arthroscopically. [0003] Cutting sutures at the appropriate location may be difficult, particularly during procedures wher...
